Abstract
A hydrogen absorbing alloy powder includes an intermetallic compound having an ABtype crystal structure and containing La for an A site element and Ni for a B site element. The powder contains La by 20 wt % or more and metallic Ni by from 2.0 wt % to 10 wt %, and acicular or grain shape precipitates containing La(OH)are deposited on a surface thereof. The powder has an intensity ratio P/Psatisfying a relation: P/P≧0.02, where Pis a peak intensity appearing in the vicinity of: diffraction angle 2θ=42.5 deg and showing (111) face of LaNiand Pis a peak intensity appearing in the vicinity of: diffraction angle 2θ=15.8 deg and showing (100) face of La(OH)in the X-ray diffractometry using CuKα rays.
